A case of a ruptured lingual artery aneurysm treated with endovascular surgery

: A rare case of a ruptured lingual artery aneurysm treated with endovascular procedure in presented. A 67-year-old woman undergoing treatment in our hospital for right thalamic hemorrhage complained of sudden swelling in the submandibular area and breathlessness. The swelling was so rapid and progressive that her breathing was disturbed. She was intubated as soon as possible. Computed tomography (CT) showed a massive subcutaneous hematoma, extending from the left submandibular area to the neck, which had compressed the trachea to the right. CT with contrast medium showed extravasation of the medium for this lesion. Angiography showed that the aneurysm was located on the periphery of the left ingual artery. Extravasation of contrast medium from the aneurysm was also observed. We considered that direct surgery was difficult to perform safely, so we chose an endovascular procedure to treat this lesion. The lingual artery was successfully embolized using four platinum coils. No rebleeding or other complication occurred after the coil embolization. Disturbance of breathing due to air way obstruction is an important symptom of a ruptured lingual artery aneurysm. Endovascular surgery may be the first choice for treatment of the bleeding origin.
